Claims

[Claims for Utility Model Registration] 1. A hollow node member in which a plurality of connecting holes are formed, a shaft portion protruding outward from the connecting holes, and a head portion rotatably locked to the node member. A connecting bolt, a connecting cylinder fixed to an end of a rod-shaped member and having a first female thread that can be screwed into a first male thread formed on the shaft of the connecting bolt, and a tip of the connecting cylinder. a sleeve having a second female threaded portion that can be screwed into the second male threaded portion formed on the side outer circumferential surface and whose distal end surface is pressed into contact with the node member; A joint structure of a three-dimensional truss node, characterized in that a columnar body having at least a pair of opposing planes is formed. 2. A hollow node member in which a plurality of connection holes are formed, a connection bolt whose shaft portion projects outward from the connection hole and whose head is rotatably locked to the node member, and this connection bolt. a connecting cylinder fixed to the end of the rod-shaped member and having a first female threaded part that can be screwed into the first male threaded part formed in the shaft part; A sleeve having a second female thread that can be screwed into the second male thread, and a space cylinder that is fitted onto the connecting bolt shaft between the node member and the sleeve, and the connecting bolt on the outside of the node member. A three-dimensional truss characterized in that a prismatic portion having a larger diameter than the first male thread portion is formed in the shaft portion, and an engagement hole is formed in the space cylinder to be externally fitted into the prismatic portion so as to be movable only in the length direction. Joint structure at the node.
